JOHN IVI. DRIVER, OF PHILADELPHIA, PENNSYLVANIA.

Application led December 23, 1921. Serial No. 524,494.

To all whom t may concern.:

Be it known that I, JOHN M. DRIVER, av citizen of the United States, residing in Philadelphia, Pennsylvania, have invented a Continuous Article Forming and Printing Machine, of which the following is a'speciii' cation.

My invention relates to machines for forming and printing paper articles-such as bags and envelopes.

The principal object of this invention is to provide a machine for forming and print-- f ing having a continuous operation and so built as to insure a proper positioning of the printed matter upon the nished article.

Hitherto in continuous forming and printing machines there has been considerable diiliculty in obtaininga proper positioning of the printed matter upon the article, and as a result it has been common practice iirst to form the article in a forming machine and thereafter to manually convey the articles to an independent printingmachine, this being the only way in which a successful article could be obtained.

I have provided a machine to which the yblank material `from which the bags, en-

velopes or other articles are to be formed isl fed at one end, said material being received properly formed and printed from the other end of the machinewith the printed matter in the desired proper position upon the article, the machine insuring great rapidity of action and a perfect finished article. f

The invention will be more readily understood by reference to the attached drawings, in which:

Figure 1, is a diagrammatic side elevation of a machine made in accordance with'my invention F ig. 2, is a fragmentary section illustrating the details of the feed from the forming mechanism to the conveyer;

F ig. 3, is a plan view of the receiving end of the printing mechanism; y

Figs. 4 and 5, are, respectively, front and side elevations of the receiving end of theA printing mechanism;

Fig. 6, is a fragmentary section of one end of the conveyer and of the receiving end of the printing1 mechanism, and 4 Figs. 7 and 8, are fragmentary sections enlarged illustrating elements and operation of 'the receiving end of the printing mechanism. l`

lnthe drawings, 1 indicatesl a frame in which is supported lmechanism for forming, in the present instance, paper bags or envelopes, said mechanism being of any of the standard and well known makes and accordingly not described herein in any detail. Adjacent the frame 1 is a frame 2 which carries the operating elements of a pair of endless belts 3 and 4, which together constitute an-endless conveyer adapted to receive the formed articles from the forming mechanism and to convey them to printing mechanism established in a frame 5, in the present instance adjacent that side of the framel opposite to the frame 5, the conveyerpalso, functioning to effect an initial drying of the adhesive employed in forming the articles to the extent of setting the adhesive and assuring its holding the parts together durino; succeeding operations. Y l

In. the present instance the conveyer constituted by the endless belts 3 and 4 passes around a pulley wheel 6 mounted in the frame 2 over a roller 7 also mounted on the frame and over and under a set of guide rollers 8, 8, which latter are mounted on a superframe 9 carried by the frame 1. The belts travel in the direction of the arrows in F ig. 1, and it will be noted that in its passage around the pulley 6 and past the guide rolls 7 and 8, the belt 3 overliesrthe belt 4 at the article-receiving end. As, h ow-V ever, the belts pass from the last of the rollers 8, the belt 3 passes under a guide roll` 10, while the belt 4 passes under a companion guide roll 11 in the opposite direc? tion, the belt 3 passingunder and over guide rolls 12,'12, carried by the frame 9 and around a guide roll 13 supported by the frame 2 to a guide roll 14, from which it again passes to the pulley 6, while the belt 4 after passing around the guide roll 11 passes over a roll 15 mounted on the frame 9, and thence over and around rolls 16, 16, carried by the frame 2 to a roll 17 forming a companion roll to the roll 14 which it underlies. l y

As' previously stated, the conveyer is adapted to receive formed articles from the forming mechanism and to conduct them to the printing' mechanism. The manner in which a formed article is fedto the convveyer is most clearly shown in Fig. 2, which l envelope or bag 18 passing between a pair of feed rolls 19, 19, which latterV dishows an rectthe-article onto the belt 4 and between the co-mpanion rollers 14 and 17, the enve-v lope 18 beingthus confined between the two belts 3 and 4, and being carried alongy with them over the pulley 6 and the various guide rollers to the guide rolls 10 and 11, at which point the belts 3 and 4 separate,permitting the article to drop into a properly constructed receptacle'in the printing mechanism.

The receptacle for the printing mechanism is illustrated, in Figs. 3 to 8, inclusive, and comprises Aa pair of adjustablel side pieces 20, 20, which flare outwardly at the top, as

best shown in Fig` `4, said side pieces having disposed therebetween a pusher head 21 of a reciprocat'ory or oscillatory pusher element 22Hthf` function of which will be describedv hereinafter.

Mounted y pieces'20 20, arev a pair of fingers 24, 24,

side pieces which latter extend parallel to the lower edges of the side pieces 20 and constitute the floor of the receptacle.

Mounted uponk a rod 25 and extending downwardly between the side pieces 20, 20, is a flexible guide element 26, said guide ele- .ment normally assuming the position in which it is shown in Fig. 7. lt will be noted that the pusher element 21, which normallythe figures by the reference numeral 18, with the bottom ledges of the article resting upon of the machine. I may provide the fingers 2 4, 24, in which position the article is in lcondition* to'be fed to, the printing mechanism.

lAs the articles drop from the conveyor into the receptacle of the printing mecha? nism, they are apt in the absence of suitable dampening means yto rebound from the fin gers 24, such rebound on occasion being sufficient to interfere with the proper operation To prevent thisv reboundas shown in Fig. 7, brushes 183,189, of camels hair or the like extending` inwardly toward each other from the opposed faces of the guide 26 and the pusher 21, said brushes meeting and constituting an efficient damper. substantially preventing rebound of the articles from the fingers while, in no way interfering with the free entrance. of the articles into the receptacle.

vThe pusher element 21 is adapted to,v be,

l oscillated forwardly into a position illustrated in Fig. 8, and operation this forward movement of the pusher occurs as each new article passes into the receptacle. This. forward. movement of the pusher 21 hasfthe effect of pushing the article 18. against the guide elementy 26, which latter, as the pusher on yarod 23 underlying theY side i advances, is, flexed rearwardly1A as shown in Fig. 8, the article 18 being carried forwardly toward the ends of the finger elements 24, 24, until eventually the lio-wer end of the article passesoff' of the end of the fingers. In this yposition of the article, the lower edge thereof is gripped by 'an automatically opflerating clampv 27 upon a feeder roll 2S mounted inthe frame 5, the article 18 thus being withdrawn from the receptacle by the' continued revolution of the, feed roll 28,v and being passed by the feed roll tothe printing mechanism in well known manner. Thefeed roll 28 with its" lamps iswell known in printing mechanism` of the type employed, and the details o-f the roll and the clamps are accordingly not described.

In Vthe present instance, referencev being had to Fig. 8 of the drawings,the pusher element 22 is shown fixed to the end of an arm` 41, which latterl is connected by means of a link 42 to a fixed arm 43. The element 2 2. also has secured to its base anarm ofa bell crank 44 on a rock shaft 45, there being secured to the lattera second arm 46 whose outerend carries a roller 47 disposed within the,` cam groove 48,y of a cam plate l49. The plate 49 rotating with the shaft 50 upon which the, roll 28 is. mounted thus provides the; movement to the pusher element.

lit Will be noted that by .reason of the kabove described receiving. means for the printing, mechanism a proper disposition of sured, thereby eliminating allpossibility of a misplacement offthe printed matter upon the article. lt will further be noted that regardless of thel position in which the bag is. received' from the forming mechanism bythe conveyer, the receptacle insures the proper positioningv of. the, article` before it passes' to the printing lmechanism.l

As clearlyshowninFig. 1,'the forming mechanism, the printing mechanism and the conveyer are. allv operated from a.- single source of power, and are so connected asto insure an absolute synchronism of movement, thisfbeing essential for the proper operation o-f the machine. In the present instance,l thev source ofv power is an 'electric motor 30, which is connected through a variable `speed transmission device 31 of. any

"suitable construction with the [forming mechanism through. a belt or other; connector 32 and with the'conveyer. elements through abelt/or. other. suitable? connector 33., the formin mechanism being .connected `with the printing, mechanism. by` means in thecombination with article forming; mecha* nism, of? printing ymechanism, conveying means for passing formed articles from the forming mechanism to the printing mechanism, and a feeding device disposedto receive articles .in an upright position from said conveying means and moving the same laterally into contacting relation with said printing mechanism. y
